If the data in Weflow's analytics and charts looks wrong, please do not hesitate to contact us via our Slack support channels or support@getweflow.com.
This can quickly be fixed. Follow these steps to clean up broken charts that were created due to incorrect amount values being added to the Opportunity history:
The records must be deleted and re-created because the wrong amount will be stored within the Opportunity history. As such, they will return if Weflow needs to re-process your data, e.g., because of changes to the fields you used or new analytics and charts we may provide.
